Agronomic characteristics of genetically modified (GM) MON 89034 × TC1507 × NK603 × DAS-40278-9 (PowerCore™ Enlist™), MON 89034 × TC1507 × NK603 (PowerCore™), and DAS-40278-9 (Enlist™) corn, a non-GM near-isogenic hybrid, and 2 commercial non-GM hybrids were assessed in a field study to determine if the agronomic performance of the GM corn hybrids is equivalent to that of non-transgenic hybrid corn. The MON 89034 × TC1507 × NK603 × DAS-40278-9 hybrid corn was developed through stacking of 4 individual transgenic events, MON 89034, TC1507, NK603, and DAS-40278-9 by traditional breeding and contains the cry1A.105 and cry2Ab2 (MON 89034), cry1F and pat (TC1507), cp4 epsps (NK603) and aad-1 (DAS-40278-9) transgenes. These transgenes encode the proteins Cry1A.105, Cry2Ab2, and Cry1F, which confer insect resistance, PAT, CP4 EPSPS, and AAD-1, which confer herbicide tolerance. The following agronomic characteristics were assessed in the study: initial and final stand count, seedling vigor, time to silk, time to pollen shed, pollen viability, plant height, ear height, stalk lodging, root lodging, days to maturity, stay green, disease incidence, insect damage, herbicide injury, and yield. The agronomic assessment was conducted in 2 regions of Brazil (Indianopolis-MG; Cravinhos-SP). The agronomic attributes for all GM entries were statistically indistinguishable from the non-GM near-isogenic hybrid. In addition, most of the agronomic assessments fell within the range of the commercial varieties included in the study. Taken together, MON 89034 × TC1507 × NK603 × DAS-40278, MON 89034 × TC1507 × NK603, and DAS-40278-9 were found to be agronomically equivalent to non-GM corn.

昆虫保护和耐除草剂的MON 89034×TC1507×NK603×DAS-40278-9玉米的农学性能与常规玉米相当。

转基因（GM）MON 89034×TC1507×NK603×DAS-40278-9（PowerCore™Enlist™），MON 89034×TC1507×NK603（PowerCore™）和DAS-40278-9（Enlist™）玉米的农艺特性，在实地研究中评估了一个非转基因的近等基因杂种和2个商业化的非转基因杂种，以确定转基因玉米杂种的农艺性能是否等同于非转基因杂种玉米的农艺性能。MON 89034×TC1507×NK603×DAS-40278-9杂交玉米是通过传统育种将4个单独的转基因事件MON 89034，TC1507，NK603和DAS-40278-9堆叠在一起而开发的，包含cry1A.105和cry2Ab2 MON 89034），cry1F和pat（TC1507），cp4 epsps（NK603）和aad-1（DAS-40278-9）转基因。这些转基因编码蛋白质Cry1A.105，Cry2Ab2和Cry1F，赋予昆虫抗药性，PAT，CP4 EPSPS和AAD-1，赋予除草剂耐受性。在研究中评估了以下农艺特性：初始和最终林分数量，幼苗活力，出丝时间，花粉脱落时间，花粉生存力，植物高度，穗高，秸秆倒伏，根倒伏，成熟天数，保持绿色，疾病发病率，昆虫危害，除草剂伤害和产量。在巴西的两个地区（Indianopolis-MG; Cravinhos-SP）进行了农艺学评估。在统计学上，所有转基因条目的农艺属性与非转基因的近等基因杂种在统计学上是无法区分的。另外，大多数农艺学评估都落在研究中所包括的商业品种范围内。综上所述，MON 89034×TC1507×NK603×DAS-40278，MON 89034×TC1507×NK603和DAS-40278-9在农艺上等同于非转基因玉米。
